oil leak on new bike left side
« on: August 22, 2014, 09:05:38 pm »
Just had my buddy pick up my new 2014.
0 kms on the odo
Theres oil in the skid plate. Seems to be coming from the gear electric switch.
Anyone else have this?
Also, are these engines loud? Like sure seems to have alot of engine noise compared to my drz even

Take the skid plate off.  Wipe the bottom of the engine dry and let it sit overnight.  You'll be able to see where the oil is coming from.  I'm betting it is the drain plug.

Could see it was clearly coming from the switch. Cleaned up keeping an eye on it to see if it keeps at it.
How much noise do these engines make?

More the a DRZ for sure. Not as noisy as an RFS but still lets you know it's running.

My guess on the source of the oil is a pinched o-ring or poor seal for the sensor to shift drum interface.  As for noise there are a couple of areas that I have found make them sound like farm equipment.  My 690 has 16,000 miles on it.  First is the rocker arms. They were making lots of noise I first thought were wide valve clearances.  Although that really didn't make sense to me.  I checked and found the problem. I've replace both intake and exhaust because the intake rocker bearing was so worn out. I could not even believe it was still running as strong as it did.  The second sourc is the crankshaft main bearing.  I'm replacing mine now.  The play wasn't sever but a definite rattle when I took the cylinder off and gave the small end of the rod a wiggle side to side and twisting side to side.  The clearance between the big end and the crank was in spec but very loose feeling.  Once chucked up in the lathe I could really make it noisy by grabbing the small end to turn the crank.  Anyway I bought a new crank and it sure is tighter and smoother.  The engine isn't back together yet.  I've heard that if a KTM engine isn't noisy then it must be broken though.  I'm hoping the engine rebuild was not a waste of time and money.  There is also another area of potential noise some 690's have exhibited and that is the balance shaft bearing surface.  I didn't have that issue.
